DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection device for preventing water and dust from entering from outside through a through hole of a wheel toward a brake device provided inside the wheel.

[0002]

2. Description of the Related Art Conventionally, as a protection device for preventing water or dust from entering from outside through a through hole of a wheel toward a brake device provided inside the wheel,
For example, as disclosed in U.S. Pat. No. 5,039,172, there is a method in which a plastic film to which a high-sensitivity pressure-sensitive adhesive is adhered is attached to an outer wall of a wheel.

[0003]

However, in the above-described protection device, the adhesive strength is reduced when, for example, the vehicle takes a long time to be transported or when the vehicle is exposed to the wind and rain for a long time. There is a possibility that the film may come off the wheels during the operation during the transportation of the vehicle, and there is a problem that the reliability of protection of the brake device is not high.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a substantially ring-shaped wheel between a wheel and a wheel cover which can close a through hole of the wheel by injecting gas into the interior. Was interposed. The bag member is provided with a separating portion which can be separated or easily separated, and a take-out portion for gas injection which protrudes outside from a through hole of the wheel cover.

[0005]

By injecting gas into a bag member interposed between the wheel of the wheel and the wheel cover to close the through hole of the wheel, water and dust are braked from outside through the through hole of the wheel. In addition to being able to reliably prevent intrusion into the bag, the bag member is protected by the wheel cover,
Moreover, the reliability of protection is improved without falling off.
In addition, by providing the bag member with a separation portion that can be separated or easily separated, and by providing an extraction portion for gas injection protruding from the through hole of the wheel cover to the outside, gas injection is easily performed. For example, the bag member can be easily removed simply by pulling the take-out portion.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a brake device according to an embodiment of the present invention; FIG. 1 is an exploded perspective view of a wheel to which a protection device for a brake device according to the present invention is applied, FIG. 2 is a sectional view of a main part of the wheel, and FIG. 3 is a plan view of a bag member of the protection device.

As shown in FIGS. 1 and 2, a wheel 1 mounted on an automobile has a brake device (brake assembly) 4 built in a wheel 3 on which a tire 2 is mounted. A plurality of bolt members 5 provided
And through the through-hole 6 of the wheel 3 and the through-hole 8 of the wheel cover 7, and tightened by the nut member 9.

[0008] A plurality of through holes 10 for cooling the brake device 4 are provided around the wheel 3 and the wheel cover 7.
11 are formed. Therefore, for example, while transporting the assembled automobile to the market by a container ship or a ferry car, rainwater, dust, etc., which enter the brake device 4 from the through holes 10 and 11 are blocked to prevent rust, dirt, etc. It is necessary to prevent a decrease in sex.

Therefore, in the present invention, a ring-shaped bag member 12 is interposed between the wheel 3 and the wheel cover 7.

The bag member 12 has an overall shape of the wheel 3.
A plurality of through-holes 10 are formed in a substantially ring shape so as to be able to be closed, and have a bag portion 13 made of a pair of film materials whose inner and outer peripheral ends are heat-welded. The gas is injected so that it can be inflated.

The bag portion 13 of the bag member 12 includes
As shown in FIG. 3, a separating portion 14 that can be easily separated is provided at one position in the circumferential direction. And this separation part 14
Is a heat welding allowance 15 extending from the inner peripheral end to the outer peripheral end of the bag portion 13.
By forming a perforated hole 16 in the heat welding allowance 15 and forming V-shaped cutouts 17 at both ends of the heat welding allowance 15, an external force is applied. It can be easily separated into two.

Further, the bag portion 13 of the bag member 12 is provided with a take-out portion 18 also serving as a gas inlet.

When the bag member 12 is mounted between the wheel 3 and the wheel cover 7, the take-out portion 18 can be made to protrude outside through the through hole 8 of the wheel cover 7. After gas such as air is injected from the inlet 18a, the gas is sealed by heat welding or a check valve is attached so that the gas can be sealed without heat welding.

In the protection device configured as described above,
When the wheel 1 is mounted on the vehicle on the assembly line, the through-hole 6 of the wheel 3 is fitted into the bolt member 5 of the brake device 4 already mounted on the vehicle, and then the bag portion 13 of the bag member 12 3 so as to cover the top of the through hole 10, and with its take-out portion 18 protruding outside through the through hole 11 of the wheel cover 7, and the through hole 8 of the wheel cover 7 It is fitted to the member 5 and tightened by the nut member 9. At this time, when positioning the bag member 12, the separating portion 14 is set at a position outside the through hole 10 of the wheel 3.

Thereafter, a gas such as air is injected into the bag portion 15 from the inlet 18a of the take-out portion 18 of the bag member 12 to inflate the bag portion 15, and when the inlet port 18 is not provided with a check valve, heat welding is performed to remove the gas. Seal.

As a result, the inflated bag portion 13 of the bag member 12 presses the inner walls of the wheel 3 and the wheel cover 7 to close the through hole 10 of the wheel 3 and to the brake device 4 through the through hole 10 of the wheel 3. Prevents rust and dirt from entering due to water and dust.

When the vehicle is completed and transported to each dealer is completed, the air or the like in the bag portion 13 is evacuated by piercing the take-out portion 18 of the bag member 12 or cutting part of the bag member 12 to remove the bag. After the portion 13 is contracted, the separating portion 14 of the bag member 12 is separated by pulling the take-out portion 18 outward, and the bag portion 13 is separated into two. Therefore, the bag member 12
Can be easily pulled out from the through hole 8 of the wheel cover 7.

The bag member may be in a state in which the separating portion is completely separated from the beginning, gas may be injected into the bag member before mounting on the wheels, or a valve inserted into the take-out portion may be used. It can be worn repeatedly and used.

[0019]

According to the present invention as described in the foregoing, a substantially ring-shaped bag member which can close the through hole of the wheel by injecting gas therein between the wheel and the wheel cover of a wheel With the interposition, it is possible to prevent water and dust from entering the brake device from the outside through the through hole of the wheel, and the bag member is not dropped and the reliability is improved. In addition, the bag member is provided with a separation portion that can be separated or separable, and by providing an extraction portion for gas injection protruding from the through hole of the wheel cover to the outside, the injection and removal of gas into and from the bag member can be easily performed. Become.
